Your support is appreciated, but I haven’t had that problem since. More commonly, perhaps once or twice per week I get into the situation where the KME is “not responding” and I notice it has grabbed 4.5-6 GB of RAM. So I have to restart the engine regularly. I guess I should be checking the logs around those times, but until now I hadn’t known about the logs at all. It doesn’t bother me a whole lot, because I enjoy the product so much every day I don’t mind an occasional fault. But I could investigate this problem now that I know about the logs.
